The 29-year-old was forced into the depot for repairs, fell off the leader lap and finished in 23rd place.

"Another tough day", says Felix Rosenqvist in a press release.

"I made a decent start and just tried to get through the first turn, but the cars in front drove together and then I was hit hard from behind by (Romain) Grosjean."

It went significantly better for Marcus Ericsson.

The 30-year-old who won in Detroit, was second after Josef Newgarden and thus managed the season's seventh top ten position.

After the summer break, the Indycar season resumes in Nashville on August 8.
